Single Use Instruments Endodontic

In single use instruments training, this question is systematically presented. Even if, as you will see, it is formally taken by the legislation, the replies are frequently worthy of a Norman since it is challenging to adopt a viewpoint. I suggest addressing this important and challenging issue in this new expert response from Endo Académie, a center for endodontic education. Contact us if you’re looking for a program to satisfy your three-year CPD requirement for dental surgeons.

You’ll likely discover it on the back, in the middle of a tonne of other pictograms, if you look at your endodontic tool pads or even a few burs. This symbol indicates that after usage, your instrument should not be re-sterilized.

Single Use Instruments For an Unspecified Purpose

When delivered in its blister, the Single Use Instruments are already sterile. It can technically be heated to 134°C in an autoclave without melting. There isn’t a problem. Why then not allow it? This has two resolutions. The instrument’s technology and mechanics are addressed first. The blades of an instrument lose their sharpness when viewed under high magnification both before and after usage. similar to periodontal curettes The metal ages and the blades become less useful after prolonged usage on tough textiles.


No. Technically, though, nothing stops it. Despite everything, these single use instruments continue to be useful, but there is also concern about their deterioration due to repeated use and uncertainty regarding the alloy’s inherent evolution due to the buildup of stresses, which weakens it and increases its susceptibility to fracture. However, the real cause is not present. The genuine explanation can be discovered in a mid-2000s book by Ove Peters who was concerned with the viability of adequately cleaning and sterilizing these tools between two patients. The issue is not with the initial usage of the instruments because they are sterile. Cross-contamination, which occurs when the patient is treated on Monday and the patient is treated on Tuesday after the equipment has been cleansed and disinfected, poses a real risk.


Ove PETERS used mouse Prion to contaminate endodontic equipment in his study. He then placed these tools through a standard and meticulous cycle of disinfection, cleaning, and sterilization of the instruments (keep in mind that the virulence of this murine prion has absolutely nothing to do with its bovine relative). Finally, he looked at these devices, and bingo, he saw a significant amount of residues of potentially contaminated trash on them.

This research was released in 2007 during a new crisis of bluetongue in sheep in Great Britain, which, let’s not forget, had just recently gone through a severe outbreak of mad cow disease and the human ailment Creutzfeldt-Jakob.

Considerable Suffering:

The British government handled the health crisis poorly, which caused considerable suffering for the French political class and the rest of Europe. The British government has mandated the single use of all blunt and piercing medical tools in response to this emerging crisis. The first to be considered are endodontic instruments. The symbol that forbids multiple uses must subsequently be added by manufacturers. Despite this suggestion, it is obvious that not many businesses adhere to this rule. And the first justification that is entirely understandable to us is the financial one. It does not, however, exempt us, the professionals, from the inherent hazards. Our dental offices are quite concerned about the cost of single use instruments as well as the ecological impact at this time when Greenwashing is in full force. Once more, the risks taken are passed to our structures with significant management difficulty.

Single Use Instruments are Endodontic

However, if we continue to think about it, we see that intra-canal, manual, or mechanical tools are not the only ones to be concerned about. Because what about tungsten carbide burs if Ove PETERS claims that cleaning a multi-blade instrument is challenging or even impossible?

Have you ever noticed how the working parts of cutters are clogged with detritus while using magnifying glasses or, more specifically, a microscope? Yet they continue to work well. These burs come into contact with biological tissues in endodontics, whether they are infected or not, as well as with the pulp, a vascularized connective tissue. What a weighty duty we carry!

In Conclusion

Should we switch to a single use for these products, to sum up. When the laws forbid us from sterilizing these single use instruments between two patients, the issue does not even come up. We still have a choice when it comes to strawberries.
